    Barack Obama did not tell the whole story this autumn when he tried to make the case that Bashar al-Assad was responsible for the chemical weapons attack near Damascus on 21 August. In some instances, he omitted important intelligence, and in others he presented assumptions as facts. Most significant, he failed to acknowledge something known to the US intelligence community: that the Syrian army is not the only party in the country’s civil war with access to sarin, the nerve agent that a UN study concluded – without assessing responsibility – had been used in the rocket attack.

    Barack Obama did not tell the whole story this autumn when he tried to make the case that Bashar al-Assad was responsible for the chemical weapons attack near Damascus on 21 August. In some instances, he omitted important intelligence, and in others he presented assumptions as facts.

    Most significant, he failed to acknowledge something known to the US intelligence community: that the Syrian army is not the only party in the country’s civil war with access to sarin, the nerve agent that a UN study concluded – without assessing responsibility – had been used in the rocket attack. In the months before the attack, the American intelligence agencies produced a series of highly classified reports, culminating in a formal Operations Order – a planning document that precedes a ground invasion – citing evidence that the al-Nusra Front, a jihadi group affiliated with al-Qaida, had mastered the mechanics of creating sarin and was capable of manufacturing it in quantity.

    The Post report also provided the first indication of a secret sensor system inside Syria, designed to provide early warning of any change in status of the regime’s chemical weapons arsenal. The sensors are monitored by the National Reconnaissance Office, the agency that controls all US intelligence satellites in orbit. According to the Post summary, the NRO is also assigned ‘to extract data from sensors placed on the ground’ inside Syria. The former senior intelligence official, who had direct knowledge of the programme, told me that NRO sensors have been implanted near all known chemical warfare sites in Syria. They are designed to provide constant monitoring of the movement of chemical warheads stored by the military. But far more important, in terms of early warning, is the sensors’ ability to alert US and Israeli intelligence when warheads are being loaded with sarin. (As a neighbouring country, Israel has always been on the alert for changes in the Syrian chemical arsenal, and works closely with American intelligence on early warnings.) A chemical warhead, once loaded with sarin, has a shelf life of a few days or less – the nerve agent begins eroding the rocket almost immediately: it’s a use-it-or-lose-it mass killer. ‘The Syrian army doesn’t have three days to prepare for a chemical attack,’ the former senior intelligence official told me. ‘We created the sensor system for immediate reaction, like an air raid warning or a fire alarm. You can’t have a warning over three days because everyone involved would be dead. It is either right now or you’re history. You do not spend three days getting ready to fire nerve gas.’ The sensors detected no movement in the months and days before 21 August, the former official said.

    It is of course possible that sarin had been supplied to the Syrian army by other means, but the lack of warning meant that Washington was unable to monitor the events in Eastern Ghouta as they unfolded.

    While the Syrian regime continues the process of eliminating its chemical arsenal, the irony is that, after Assad’s stockpile of precursor agents is destroyed, al-Nusra and its Islamist allies could end up as the only faction inside Syria with access to the ingredients that can create sarin, a strategic weapon that would be unlike any other in the war zone. There may be more to negotiate.
